Selective solar-driven CO2 reduction mediated by 2D/2D Bi2O2SiO3/MXene nanosheets heterojunction
文献摘要：
Photocatalytic CO2 reduction reaction(CO2RR)is an environment-friendly technique for clean fuel genera-tion.Developing low-cost and efficient photocatalyst/cocatalyst systems for boosting CO2RR is still a chal-lenge.Herein,a novel Bi2O2SiO3/Ti3C2 2D/2D heterojunction photocatalysts are successfully prepared by in situ growth of Bi2O2SiO3 on the surface of ultrathin Ti3C2 nanosheets,a kind of MXenes.The observed Bi2O2SiO3/Ti3C2(BOSO/TC-2)hybrids exhibit a large interface contact area companied with enhanced CO2 adsorption capability,illustrating excellent 2D/2D interfacial charge transfer behaviors.The total yield of products obtained on the optimized BOSO/TC-2 photocatalyst is 3.8 times that of pristine Bi2O2SiO3 nanosheets and achieve near 90％selectivity for CO over CH3OH without sacrificial agents,which was higher than most all inorganic Bi-based photocatalysts.Moreover,the mechanism of enhanced photocat-alytic activity and reaction pathway was proposed in terms of the DFT study and in situ FTIR analysis.This work might provide new semiconductor/cocatalyst systems for selective CO2 photoreduction to solar fuels.
